T0 all whom it may Concern.'

-Be it known that I, EDWIN M. BAssLER, a citizen of the United States, and a resident 'of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Heating Apparatus, of which the following is a specification.

This invention relates to heat generators and radiators, and relates particularly to generators and radiators designed and adapted for use in connection withsystems or apparatus for hot air heating and ventilating by forced circulation.

rlhe principal objects of the invention are to increase the efficiency of the heat generating and radiating apparatus; to simplify the construction and reduce the cost thereof; to provide a; heat generating and radiating apparatus which shall be relatively small, compact and self contained; to prevent loss of heat by radiation; to obviate danger from explosions; and to provide a generator and radiator which may be operated without an expert engineer and with a minimum of work and attention.

Considered broadly,l I effect the foregoing objects by combining a generator with a radiator so as to form a unitary structure and in such manner that the heating medium will pass directly from the generator to the radiator, thus dispensing with all pipe connections between said generator and radiator, and also maintaining this heating medium practically at its maximum temperature, so that, when it is returned to the generator, but very little heat will be required to again convert it into steam. Specifically said invention consists of the various features, combinations of features and details of construction hereinafter described and,

claimed.

In the accompanying drawings, in which my invention is fully illustrated,

Figure l is a side elevation of a combined steam generator, radiator and blower, illustrating the application of my improved apparatus for hot air heating by forced draft or circulation.

Fig. 2 is a central, vertical, longitudinal section thereof. y f

Fig. 4 is a sectional elevation on the line 4 4 0f Fig. 2.

sectional view on the line 6 6 of Fig. 4.

Referring now tothe drawings, in which I have shown what I now consider to be the preferable embodiment of my invention and preferable means for applying same for use in` a system of hot air heating and ventilating by forced circulation, I will first describe in detail the construction of the generator and radiator and will then describe the setting therefor and the manner of applying same for use.

The body portion of my improved generator and radiator, designated as a whole A, 1s hollow and comprises legs or sections A, A2 which extend lsubstantially at right angles to each other. Said body portion will hereinafter be referred to as a header.

The interior of said header A is divided into compartments by means of a partition comprising sections A3, A4 in the legs A, A2, respectively. From the point of juncture of the sections of said partition, the partition section A4 is continuous to the end of the horizontal leg A2 of the header, while the section A3 preferably terminates about two inches short of the lower end of the vertical leg A of said header, thus permitting the water columns on opposite sides of said partition A3 to equalize and also providing for draining the said body portion, when desired.

For convenient reference the compartments in the leg A formed by the partition A3 are designated, respectively, a, a and the compartments formed in the leg A2 by the partition A4 are designated, respectively, a2, a3.

Secured to the wall l of the leg A are tubes 2, the inner ends of which are in open communication with the compartment a of said section A and theouter ends of which are closed; and secured in the partition section A3 are tubes 3,said tubes 3 being smaller than the inside diameters of the tubes 2 and extending into said tubes, and being preferably of such length that they will extend to within a short distance of the closed outer ends of said tubes 2. Both ends of the tubes 3 are open, said tubes thus connecting thel compartment a of the leg A with the 1nteriors of the tubes 2 adjacent to their closed ends, and through said tubeswith the compartment a of said header leg A-.

The pipes 2 are of proper size to provide adequate heating surface and to produce a desired velocity of water circulation therein to secure eiicient and economic operating conditions. Also, I preferably use relatively large tubes at the extreme front end of the generator where the heat is most intense, said relatively large tubes being designated 2 in the drawing and the tubes which extend inside thereof 3. For ordinary uses, desirable sizes of tubes are about 2 inches for the tubes 2v and of an inch for the tubes 3', and 1i inches for the tubes 2 and of an inch for the tubes 3. f

The tubes 2, 2 extend beneath the leg A2 of the header A and are of such length that they will terminate slightly short of the end of said leg.

In like manner, tubes 4 are secured in the upper wall 5 of the leg A2 of the header A, the inner ends of said tubes being in open communication with the compartments a,a of vsaid body portion and the outer ends thereof being closed; and secured in the section A4 of the partition wall are tubes 6 both ends of which are open and which connect the compartment a2 of'the leg A2 with the interio-rs of the pipes or tubesi 4 adjacent to their closed outer ends.

For convenience and economy in constructing different sizes of generators and radiators embodying my invention, I preferably make my improved generator and radiator in the form of similar separate units, any number of which may be connected together, in the relation shown in Fig. 1, to form a generator and radiator of any desired size. I do not desire to limit myself to this construction, however, as my invention contemplates the use of headers made in one piece regardless of their size. The preceding description has particular L reference to a single unit and applies equally to all of the units and I shall therefore apply the reference letter A to designate the body portion of each unit as Well as of the entire structure, which may consist of a single unit or of a plurality of units.

In the preferable construction shown, the units A are connected to form a unitary structure by bolts 7, the nuts threaded to the ends of which afford convenient means for drawing said unit sections into close contact with each other and` to provide for equalizing the water level and the steam pressure in the different units, said units are connected so as to communicate with eachl be forced or drawn into tight engagement With corresponding tapered seats formed in openings 9 in the adjacent wallsof said generator units. In the preferable construction shown, three bolts 7 are employed and the headers A of the generator units are provided with three sets of openings 9, the holes of each series being arrangedoin alinement with each other, thus forming a continuous hole from end to end of the generator through which the connecting bolts 7 extend, and the nipples v8 being enough larger than the bolts 7 to form communicatingy openings of desired size between the different units. In ordinary practice, I use bolts and 3 i. d. nipples. Also, the joints between the different Aunits are sealed with cement which will hardenl under heat, thus preventing the products of combustion', smoke, gases, etc., from passing from the Acombustion chamber of the furnace to the inclosed space which contains the heating v tubes, as will presently appear.

In setting my improved generator and radiator, the leg A is disposed vertically and the leg A2 horizontally, the pipes 2, 2 extending horizontally beneath the leg or section A2 and the pipes 4 extending vertically from the` upper side of said leg or section A2.

While my invention contemplates anyV suitable setting for my improved generator and radiator, I prefer the setting shown in the drawings, which I -will now describe. The lower end of the header leg A rests directly on the foundation and forms part of the side wall of the furnace setting. The outer end of the horizontal leg A2 is supported by a plurality of plates or panels 10 the lower ends of which rest on the foundation and the upper ends of which are inserted beneath a rigid part formed'by separate flanges onl the outer end of each unit section A and said plates or panels are connected together and to the header by bolts inserted through flanges l2 formed at the margins of said plates or panels 10 and through the flanges or brackets 11 on said header and the flanges 12 on the upper edges of said plates or panels. The settingv walls are extended frontward and a short distance rearward from the generator, both lateral Walls thereof being formed by plates or .y panels similar to the plates or panels 10 and secured to each other in the same manner, and the top thereof is formed by arched plates 13, of the same Width as the plates or panels 10 and which comprise end sections 14 which extend downwardly from the main parts of said arched plates-on substantially radial lines. Like the side plates or panels 10, the top plates 13 are adapted to be secured to each other and to the upper ends of the side panels and to the walls of the end generator and radiator units A by means of cap screws or bolts inserted through flanges formed. entirely around the edges of said top plates 13 and, at the ends,

through the flanges 12 on the upper edges.

of said side plates or panels. The front 'and-back top plates adjacent to the eXtreme front and back heater units A are secured directly thereto by cap screws inserted through the flanges 15 on adjacent edges of said top plates and which are threaded into suitable screw threaded holes formed in the wall of the header.

` The front of the setting is closed by a front wall 16 provided with usual firebox and ashpit doors and the rear end of said setting is closed by a` rear wall 17 provided with a smoke stack opening 18 andadjacent to its bottom with a cleaning door 19.

Said front and rear walls are connected to the adjacent top and side plates by means of bolts or ca'p screws inserted through the edges thereof and through the marginal flanges on said top and side plates.

The side plates 10, top plates 13 and'front and rear walls 16 and 17 are preferably made of castiron and the joints between adjacent plates are rendered tight lby means of suitable cement.

A bridge wall 20 dividesthe interior of the setting into a usual fireboX and ^combustion chamber and supported within the furnace are usual grate bars 21 on which the fire is suppprte'd and beneath which is the ashpit.

The cast iron walls of the setting are projected by means of linings of suitable refractory material. While my invention y contemplates the use of any desired or used form Aof linings, l prefer the form shown,

' which consists of plates made of re clay of substantially the same size and shape as the inner side Iof said side panels and top plates. In the preferable shown, the side plates or panels have linings designated 22 which are adapted to be held in position on the inner sides of the side plates or panels 10 in the following manner Formed on'the lower endsV of said side panels are linwardly projecting flanges 23 on which the lower ends of the linings 22 y rest, the inner ends of said flanges 23 being turned upwardly as Vshown at 24 to. vform shoulders or ledges adapted to hold the lower ends of said linings 22 in position on said flanges 23. At their upper ends the lining plates 22 are inwardly and downwardly beveled as shown at 25 and .are1

adapted to interlock with correspondingly inclined surfaces on the linings of the top plates 13 and on theo'uter ends ofthe horizontal leg A2 of the header A. As shown,

"the linings for the top plates 13 consist of platesl26 which are lcurved to correspond with the arches of said top plates 13 and the ends of which fit closely against the inconstruction clined ends or shoulders 14 of said top plate, whereby said top lining plates will be held in position by means of a dove-tailed connection therewith, see Fig. 4, and also by means of the inclined surface 25 at the outer ends of said plate linings.

To provide for operating my improved generator and radiator bymeans of forced draft, a chamber 27 is formed in the bridge wall 20, which communicates with the ashpit of the furnace by means of openings 23 My improved generator and radiator will/ be preferably provided with usual steam and water gages, safety valves, automatic air vents, blow-o cock and automatic damper regulator.v These, however, form no part of my present invention and can readily be applied by any skilled mechanic familiar with this line of work.

To provide for observing the interior of the combustion chamber, peep holes indicated generally at 31 and which are adapted to be covered by suitable pivoted shutters designated 32 are provided in the side plates 1() which support the ends of the leg or section A2 of the generator.

The heater tubes 4`are inclosed by a suitable casing -33 preferably made of galva- .nized iron or the like and which is provided at one end with a blower connection 34 and at its opposite end with a discharge 'opening 35 to which a discharge pipe, not shown,

`is adapted to be connected.

To provide for tempering the air dischargex from the casing 33, said casing is preferably divided longitudinally by a horizontal vpartition 36 which separates the interior thereof into a chamber 37 in which the heating pipes 4 are located and in a cold j air passageway 38, the relative amounts of air passing through the chambers 37 and 38, respectively, being controlled by means of dampers 39 and 40 which control the discharge ends of said chambers or passageways, respectively. In practice saiddampers are preferably controlled automatically by suitable means provided for the purpose. Means for this purpose are old and well known and, as they form no part of my invention, and can readily be supplied by persons familiar with the art, such means are not shown in the drawings. I

Connected to the admission opening of iso lthe casing 33 which incloses the heating tubes 4 is the discharge end of a fan or blower by means of which a forced circulation of air may be maintained through said casing 33 which communicate with the discharge opening of said casing.

. In the preferable construction shown, the fan or blower, designated B, is mounted directly on the top of the setting at the front side of the header A of the generator and is adapted to be driven by an electric motor mounted directly upon the fan casing.

Vhile I conside` the foregoing arrangement for the fan and blower to be preferable, I do not desire to limit myself thereto, as my invention contemplates supporting the fan in' any desired relation to the generator and driving thesame in any desired or approved manner.- u

As shown, the chamber 27 in the bridge wall 20 is connected with the fan casing by means of a pipe 41' connected to the opening 29 at one end with a corresponding opening in the fan casing at its opposite end. Said pipe is controlled by means of a suitable slide or damper 42 by which the amount of air supplied to the chamber 27 may be regulated'as desired.

The normal water .level in the generator is somewhat above the bottom wall of the horizontal leg or section A2 of theheader A and is' indicated in the drawing by the line F ig. 3.

With the described construction, it is obvious that all of the pipes 2 and 3 and the chambers a, a1 and a2 to the height of the line will be full of water and will be heated to a high temperature by Contact of the fire and products of combustion with by the current of air the pipes 2, and with the inner wall vl of the vertical leg and the lower wall of the horizontal leg of the header, all of which are eX- posed to the direct action of the heat and products of combustion passing from the furnace to the stack opening. As the water is converted into steam, it rises into the chamber a2 above the level of the water and passes thence upward through the inner tubes 6 into the upper ends of the heating ,tubes 4 and is Wholly or artially condensed rom vthe blower B passing-among and around said pipes. As said steam condenses, the water drains from the pipes 4 into the chamber a3, and thence along the partition A4 into the chamber a1 and into the main body of water. From said chamber al the Water flows outwardly through the pipes 3 into the outer ends of the pipes 2 and back through the pipes 2 into the chamber a., where it is again converted into steam. Due to the fact that the generator has practically no radiating surface excepting the radiator tubes 4, it is obvious that the condensed water which drains into the chamber alwill be only slightly below the temperature at which it will pass maintaining a supply of steam and, owing to the fact that there is practically no loss of heat by radiation in the passage of the steam from the generator to the radiator, the air passing through the casing 33 will be heated to the highest possible degree, thereby resulting in the highest possible efficiency and economy in the operation of the apparatus.

In addition to its very high efliciency, my improved generator and radiator possesses important advantages over any system of heating by forced circulation of air of which I have any knowledge in the respect that all piping and fittings heretofore necessary for connecting a boiler with the heating coils are dispensed with, thus effecting a material saving both in material and labor and also very greatly reducing the space occupied by theseparate boilers, heating coils, blowers and motors as heretofore used. Moreover` the operation of my improved generator and radiator requires the attention of an operator merely for stoking the furnace at intervals as may be necessary, all other functions of the generator being automatic and self adjusting.

' While I consider the form of my improved generator and radiator herein shown and described as being the preferable embodiment of my invention, it is possible that in view of my disclosure, other forms of apparatus could be readily devised by skilled mechanl ics for carrying out my said invention and I do not therefore, desire to limit myself to the exact formof apparatus herein shown and described, but desire to include all forms of apparatus by which my said invention may be carried out.
